Tablesorter math widget use data-*

Question

I am using Mottie's Tablesorter (https://github.com/Mottie/tablesorter) and i am trying to use the Math widget on cells that are formatted like this;

<td data-number="50">Fifty</td>

However i cant seem to find out how to pass data-* through to arry on the math-complete option;

  math_complete : function($cell, wo, result, value, arry) {
    var txt = '<span class="align-decimal">' +
      ( value === wo.math_none ? '' : '$ ' ) +
      result + '</span>';
    if ($cell.attr('data-math') === 'all-sum') {
      // when the "all-sum" is processed, add a count to the end
      return txt + ' (Sum of ' + arry.length + ' cells)';
    }
    return txt;
  }

Also, I am using v2.18.2.

The math widget is set up to get information from a data-attribute set by the textAttribute option. So if you want to use data-number, set that attribute to "data-number" (demo):

$(function () {
    $('table').tablesorter({
        theme: 'blue',
        textAttribute: 'data-number',
        widgets: ['zebra', 'math']
    });
});
